Abstract: The global electronics manufacturing industry is entering a period of intensive innovation and rapid development of emerging companies. With the rapid development of component packaging, more and more PCBA are widely used, and PCB SMT assembly technology is also developing rapidly. In t...
Abstract: RoHS is a mandatory standard established by EU legislation. Its full name is “Restriction of Hazardous Substances” (Restriction of Hazardous Substances), which is mainly used to regulate electrical components in pcb assemblies. The product material and process standards make...
Abstract: With the development of electronic product PCBA assembly towards miniaturization and high assembly density, SMT surface mount technology has now become the mainstream technology of electronic assembly. However, due to the large size of some electronic components in PCBA ASSEMBLY process...
Abstract: In PCBA processing, pcb smt wave soldering is to make the soldering surface of the plug-in board directly contact high-temperature liquid tin to achieve the purpose of soldering. The high-temperature liquid tin maintains a slope, and a special device makes the liquid tin form a wave-lik...
Abstract: The quality of PCB solder joints in pcb assembly processing is the most important thing. The reliability of solder joint quality determines the reliability and service life of PCBA products. Once the solder joint fails, the pcb assembly will face the situation of repairing or scrapping....
Abstract: With the rapid development of science and technology, the iterative speed of electronic technology products is changing exponentially. For a product, there is often not much time for trial and error. The best way is when the design is completed. After that, conduct PCB assembly proofing...
Abstract: The role of PCB assembly in modern high-tech products is becoming more and more important, and users have higher and higher requirements for electronic equipment. Professionals who understand PCBA electronics manufacturing knowledge can help design designs that are more in line with cus...
Abstract: PCBA testing is an important part of the PCBA process to control product quality. It is to check whether the custom PCB Assembly board has sufficient reliability to complete future work. This will directly affect the future user experience and repair rate, so PCBA reliability testing a...

Abstract: SMT is the core link in PCB production and is a surface assembly technology. SMT PCB Assembly mainly refers to attaching components to the PCB printed with glue or solder paste through the placement equipment and then passing through the soldering furnace. GA soldering is an important p...
Abstract: Here is a summary of various inspection standards in the PCBA processing industry, which are introduced in detail from the main aspects of PCBA component design and inspection specifications and PCBA general appearance inspection specifications. Follow Kingford to learn more about them....
Abstract: Stencils, also known as SMT stencils, are special molds for SMT Stencil of PCB Assembly. Its main function is to help the deposition of solder paste; The purpose is to transfer an accurate amount of solder paste to an accurate position on the empty PCB. Laser stencil is currently the mo...
